ASSIGNMENT 3

QUESTION 1 (30 marks)
a) (20 marks) Construct the Axial Force, Shear Force and Bending Moment Diagrams for
the frame shown below. Assume joint B as rigid. Show your working clearly and
indicate the location and magnitude of the maximum bending moment on the
appropriate diagram.

b) (10 marks) Determine the internal normal force, shear force, and moment at point C in
the simply supported beam. Point C is located just to the right of the 1500 kNm couple
moment.

QUESTION 2 (30 marks)
a) (15 marks) Draw the shear and moment diagrams for the simply supported beam.

b) (15 marks) Draw the shear and moment diagrams for the beam shown below.
QUESTION 3 (20 marks) Draw the shear and moment diagrams for the following beam.
